Eaton 10kΩ Rotary Potentiometer Front Mount, 232233 M22S-R10K

Eaton’s M22 range of rotary potentiometers enable a user to regulate and change the current that flows through a circuit, these rotary potentiometers can be easily controlled by turning the adjustable spindle or knob. These potentiometers are panel mount with screw terminals for easy mounting inside control panels and other electronics.

A potentiometer is a variable resistor that increases or decreases the resistance in an application. Usually available as either digital or analogue, there are many different types of potentiometer but the two main types are rotary and linear.

• Linear - comes in a rectangle strip shape and can be pulled up or down for the required resistance, used a lot within sound systems for mic output or volume control.
• Rotary - the shaft is housed by a knob, you would find these on dimmer switches or speakers, and turning (usually to the right) will increase the resistance amplifying the output, whether that is light, sound or voltage.

Potentiometers have two terminals that are fixed to a resistive element (the track). The resistive element is typically wire wound or made from carbon, cermet or conductive plastic. The third terminal is connected to the wiper, which is a sliding contact. As the wiper moves along the track, the resistance changes and the current flowing through the circuit changes.

Regulate electric currents flowing through your circuit with this Eaton rotary potentiometer. The unit offers a maximum resistance of 10,000 Ω and a 0.5-watt power rating. It features a precision-control, adjustable spindle to amplify or limit the resistance and output. This is a reliable choice for controlling frequency attenuation and volume in devices such as radios and stereos. You'll also find units like this managing light intensity in dimmer switches, and heat and cooling levels in temperature controls.

• Front mount and 0.22 mm mounting hole diameter for easy fitting in control panels
• Screw terminals mean you only need a screwdriver to complete installation
• Easy spindle handling, with a shaft length of 32.9 mm and diameter of 29.5 mm

Potentiometers feature three terminals, two of which are fixed to a resistive element such as wound wire or conductive plastic. The third terminal is connected to a wiper to adjust the flowing current. A rheostat, by contrast, is a two-terminal variable resistor that typically handles higher currents and voltages.

This unit's IP (ingress protection) rating of 66 means it's dust-tight and completely protected from low-pressure jets of water.
